MACHINE FOR AFFIXING- SHOE-HEELS.

Specication of Letters Patent.

Patented Jan. 25, 1921.

v Application led October 21, 1920. `Serial No. 418,438.

Be i known that we, .IoHN Il. Pnnoand V'Isrsenicnn IInNNn, citizens ofthe United States, residing in "the cityl and Stateof New Y rk, havejointly invented a new andv useful Improvement inMachines for AiiixfingShoe-Heels, of which thel following is a speciiication.

. Thisfinvention relates to a machine' for; aiiixing shoe heels, vandlsmore particularly.

an improvement upon and vwithin the machine disclosed vin applicationfiledV March 31st, 1920,'SerialNo- 370,269. The object is to providesuch a Vmachine with improved clutch means. for 'holding theheel-pressing members,- 4after being depressed, in ksuch manner that theclutch seizesand holdsrej liably at any point. A further object 1s toprovide a simple, strong vand long-Wearing construction,l for thispurpose. Other objects Vand featureslwill become apparent as Y y'thespecification proceeds.

In the accompanying drawings, forming--V a part hereof:

in central vertical section, showing only two copera-tive heel-pressingmechanisms, one

Figure 1 is a 'view of the machine, mainly of the circular series ofshoe-mounts and the of the latter being raisedand the other depressed; Y

Figm2 is an enlarged fragmentary elevatiOnincludingthe clutch meansVseen at the Fig.n 3 is a vertical longitudinal sectionl ithrough Fig.2;

, Fig."4 4is a horizontal section on the line Hofrigemnd Fig. 5 is asectional end ViewY of clutch.` The machine has a pedestal 1 risingfroma base 2 and rotatably supporting a table 3.

The latter is adapted to be turned in a stepby-step manner and hears acircular series of shoe-mounts, including the tiltable last- Y supports4 and toe-rests 5. The lasts 6 bear# ing the shoes are placed upon thepins` 7y fof theflastsupports, with the toes resting f upon the;toe-restslA A corresponding'- circu-` f lar or radiating series ofheelLpressing arms' '"8 are fulcrumed at their inner ends in an4elevated hub 9l supported from and rotatable Y, with the central part ofthe table by pillars f 10, and are adapted to 'be depressed by rods 11ypivotedto the arms and passingwerti- "their forkedfa'nd padded outerextremities cally downward vthrough openings "1n the table.' When thesearms are pulled down,

12 are caused to bear upon the sloping backs of the heels, as seen atthe left in Fig. 1, for the purpose of clamping the heels to the shoebodies until the cement is set.

. The rods 11 are depressed successively when they come in front of theoperators station by means of a treadle 13 and a rod 14 slidable inbrackets 15 on the standard 1.

The rods 11 pass into and lout of operative rrelation to the rod 14 asthetable is turned step by step, by virtue of heads 16 on the lower endsof the rodsr11 and a yoke 17 on the upper endv of the rod 14, a spring18 acting te sustain the rod 14 at the proper height, so that the headsmay enter laterally within the yoke when said heads are in their upperposition, as determined by stops 19.

When the operator forces the arms 8 down upon the heels and thenremovesthe foot pressure from the treadle, it is impor- Vtant that theclamping action of the heelpressing members be preserved withoutslipback Aor relaxation until such time as it should be desired toremove the shoe. For this purpose the means about to be described,constituting the more particular novelty of the present invention, fareprovided.

At the region where each of therods` 11 passes through a guide openingin the table, there is a flat clutch plate 2 0 lying loosely Vupon thetable and provided in its outer 'suchfmanner as to lpermitV slighttilting movement the'reojll Vwhile preventing bodilyV Y upward movement.The rear endv of each plate is slotted or notched, as indicatedfat 27,to coperate with a' pin 28 projecting downward .from the block tolconstitute vmeans for preventing lateral'displacement of the plate.Each plate is normally tilted upward by a spring 29 contained in arecess 30 in the-table beneath the plate. Manual means are provided `forpressing each of the clutch plates downward so as to releasel thecorresponding'rod 1 1, thesaid means in moved from the treadle l3,`tlheclutch plate Y 2O immediately grips vand holds immovably theVcorresponding rod 11, the .gripping acv tionftakhing p laceat thediagonally opposite thereby pressing the xplate down 'Hat upon 'a and bkis removed. j
